Sergeant wounded after 'disturbed' off-duty officer grabs gun in underpass scuffle A police sergeant was shot in the thigh last night by an emotionally disturbed off-duty constable who grabbed another officer's revolver in a scuffle in an Aberdeen underpass, police said. Suen Wai-leung, 39, who was on sick leave and had been reported missing by his family, was disarmed by the wounded sergeant and another constable. The shooting came six months after the force was shocked by a shootout in a Tsim Sha Tsui underpass, also involving an off-duty officer, which left two constables dead. It also came after three days of bizarre behaviour by Constable Suen, in which he quarrelled with his wife, crashed his car and ran away from his family. Constable Suen, a policeman for 19 years, is attached to the patrol sub-unit of Happy Valley police station. He had been on sick leave since Tuesday. The scuffle broke out when the two patrolling officers, both members of the crack Police Tactical Unit, encountered Constable Suen in the subway on Aberdeen Praya Road at about 6.30pm and he fled. He had gone missing for six hours on Tuesday after his car was found crashed down a slope in Nam Long Shan Road, Aberdeen, at about 9am. He was found in Aberdeen Praya Road at 3pm that day and taken to Queen Mary Hospital for a checkup. District Commander (Western) Winnie Chiu Wai-yin said family members took him back to the hospital for an examination at about noon yesterday. 'When their taxi reached Tin Wan, he suddenly jumped out of the cab and then went missing,' she said. In the subway confrontation, Constable Suen scuffled with the two officers and managed to snatch the other constable's revolver when they tried to stop and search him. 'There was a scuffle. The off-duty officer took control of a gun from one of the patrolling officers and fired a shot, hitting the thigh of one of them,' said Stephen John Baker, acting assistant commander of Western District. Constable Suen was chained to a stretcher after being subdued and was under guard in Queen Mary Hospital last night. 'The policeman has emotional problems. He fired a shot in the subway,' Ms Chiu said. The injured station sergeant, surnamed Wong, 44, was also in Queen Mary recovering from his leg injuries. The second constable, surnamed Ng, 31, was not hurt. On Monday, Constable Suen had a dispute with his wife, 33, over family affairs and pushed her out of their flat in Aberdeen Centre, police said. Legislator James To Kun-sun, chairman of the Legislative Council's security panel, said the police should do more for officers with emotional problems. 'If the force does not have comprehensive information on officers with problems, they should work on it. They should also try to find out the causes of the problem so that help can be offered,' he said. Dennis Wong Sing-wing, programme leader of the criminology course at City University, believed Constable Suen had probably grabbed the gun as he felt he was forced into a dead end by the policemen who confronted him. Police did not say how long they had been aware of the constable's emotional problems. Mr Wong urged the police to be more alert to disturbed officers. 'If the force knows that a policeman, even occasionally, shows signs [of emotional distress], they should invite the officer to undergo a psychological exam and also offer counselling services that are outside the police station,' he said, noting that police provided counselling only internally and did not offer external services. 'If counselling is within the police station it gives the impression there won't be confidentiality, so people may be reluctant to seek help.'
